To all whom, 'it may concern:

Be it known that I, WILLIAM R. CHNCEL LoR, a citizen o'f the United States of Amen ica, and a resident of Chicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in Floor-.lla-xing Machines, of which the following yis a specification.

This invention relates to portable power operated machines for waxing and `polishing floors. The purpose of the invention lis to provide a light, complete machine, which may be easily manipulated, and well adapted to take the place of manually operated devices for waxing and polishing floors, and

thereby saving immense labor in such work. It is also a purpose ofthe invention to provide a. simple and efiicient means for'feeding wax from a wax container on the machine, in the required quantity to a brush which serves to apply the wax to the floor before it is spread and polished by a separate brush carried by the machine; and 'to provide a convenient means for causing the wax applying brush to become operative and inoperative, as required, and to raise and lower the brush out of and into contact with the iioor.

The. objects of the invention are fully attained by the constructions such as shown in the drawing, wherein:

Fig. 1 is a plan view of its casing removed. l

Fig. 2 is a side view ofthe construction shown in Fig. 1. l

Fig. 3 is a longitudinal sectional detail showing the wax supply container and wax applying brush cooperating therewith;

Fig. 4 is a side view of a spraying and polishing brush having a cloth covering applied thereto which is used for the final polishing operation.

The principal features of the construction as may be seen from the drawing, are a suit- -able supporting base mounted upon casters of suit-able height for making room for the rotating brushes mounted below the supporting base. One of these casters is free to swing around a vertical axis sothat the mathe machine with chine maybe easily'guided intothe desired direction. A motor is mounted upon the supporting base, and is belted to a vertical spindle ada ted to removably receive spreading and polishing brushes. Intermediate the motor andsaid vertical spindle is a wax supply container, and below this container on 5f a horizontal axis is a wax vapplying brush. This brush is carried by an arm pivoted to the supporting frame, so that it may be swung downwardly against spring action from its normal position, into contact with 60.

the floor. Such motion is transmitted to the waxing brush at desired intervals .by the operator drawing upwardly on a lever hinged to the operating' handle of the maf' chine, by which the machine is guided over the floor, this lever being connected by a wire with the waxing brush supporting arm. The downward 'motion of the waxing brush causes a pulley belted thereto to come into engagement with the driving belt for the 7 purpose of rotating the waxing brush. The wax container is slidably mounted above the waxing brush in' order to follow the same in its downward and upward motions,` and is preferably provided at its lower side, i

where it cooperates with the waxing brush with longitudinal slots or some similar arrangement for allowing only a limited contact between the brush and the wax.

The bottom of the wax container is partly SAO curved around t-he'waxin brush and provision is made for adjusting the container horizontally toward the brush so that its lower edge may serve to wipe oii' the excess wax from the brush.

As illustrated in the drawing, the above mentioned arrangement includes a supporting base 1, provided with casters 2 and 3, the latter being swiveled for rotation around a vertical axis. upwardly from one end ofbase 1, and is provided with a grip 5, to which is pivoted a small-arm or lever 6, which may be drawn upwardly toward the grip 5 by the fingers of the operator. The arm 6 is connected by 95 Aa wire 7 passing through a flexible conduit 8, with a lever 9 pivoted to the platform 1 at 10. .Rotatably mounted in the lower end of lever 9 is a waxing brush 11 carrying a pulley 12, and at the upper end-of arm 9 is a 100 pulley 13, connected 'with pulley 12 by a belt 14. Rigid with pulley 13 is another preferably larger pulley 15, in position for engagement with a drive belt 16, when the arm 9 is rocked to carry the waxing brush downwardly. yThe arm 9 and parts carried there- The guiding handle 4 extends 90 vbase l.

by are normally held in the position in which they are shown in Fig. 2 by the spring 17. The driving belt 16 passes around a motor pulley 1S, idler wheels 19, and a pulley 20, v

normally remains idle, because the pulley 15 is normally out of Contact with belt 16. `When the lever 6, attached to the grip 5, is drawn upwardly, pulley l5 becomes etlective with respect to belt 16, and motion from the pulley 15 is transmitted to the brush11, through the belt 14 and pulley 12.

A suitable opening 24 is provided in base 1 at 'the location of the waxing brush 11, and a wax receptacle 25 is mounted above-the brush at4 this opening. This receptacle is in box form, and provided with an aperf tured flange 26, through which passes vertical posts 27, extending upwardly from the The receptacle is free to slide upon these posts and therefore moves up and down with the wax applying brush 1l.

The wax container 25 is more or' less closedat the bottom, and the point of contact` with.

the brush 11, preferably by a plurality of longitudinally I extending and upwardly curved wires 28, or other suitable means for leaving openings or longitudinally extending slots 29 at the bottom of the container. The bristles of the brush 11 may extend slightly into the slots to pick up a limited quantity ofwax during rotation ot' the brush. The feed of the wax toward the brushl is slowly provided for by a movable weight'29, resting on the upper surface of the wax 30. When the wax brush supporting arm 9v is swung by meansof the connection with arm 6 at handle 5, downward motion of drive belt 16 is limited by an idler 31.

The posts 27 upon which thewa-x container 25 is slidably supported, are connected together at their lower ends by a part 32 extending at right angles to the posts into a slot 33 in platform 1. This arrangement provides for adjustment of 'the wax container so its lower edge 34 may be brought more or less into contact with the ends of the bristles of brush 11 and serve to limit the amount of wax carried downwardly by the brush. The set screw 35 is for permanently fixing the structure after the adjustment is made. v

In Fig. 4, a brush such as the spreading or polishing brush 22, is shown provided with a cloth cover. 32, which arrangement is employed for the linal polishing operation. This cover Ais merely in the form of abag, having an elastic band hemmed into it at its open end 33:"

The motor receives current through a flexible l conduit under the control ot a switch 34, as is common in vacuum cleaners 22', but brush 11 is only driven at such times as it is lowered by drawing the lever 6 toward grip 5. In waxing a floor 1t is necessary to only occasionally lower brush 11,V

for instance, in order to apply a small quantity of the wax; then brush 22 is utilized for evenly spreading 'the wax. After the spreading operation is completed, other brushes are applied to spindle 21 for polishing. When brush 10 is lowered by drawing on wire 7, pulley 15 is drawn into engagement with belt 16, resulting in transmitting rotary motion to the brush 11 'through the belt 14. Rotation of the brush causes it to carry wax from the container- 25 to the floor, this container being free to follow the brush in its downward motion.
